78807520 divided by 315 
We want to divide 78807520 by 315.

Moving on to step 1:
7 divided by 315 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 315

On to step 2:
If we divide 78 by 315, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 315

Step 3:
When dividing 788 by 315, we get 2 with a remainder of 158.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 630 away from 788, we end up with 158.
Take the next digit (0) from the dividend and append it to 158, then repeat: 1580 / 315

Let's proceed to step 4:
The number 315 fits into 1580 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 5 after subtracting 1575 from 1580.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 315

On to step 5:
When dividing 57 by 315, we get 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 250.0
Deduct 0 from 57 and we're left with 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 315

On to step 6:
If we divide 575 by 315, we get 1 and a remainder of 260.
The number 1 becomes the next digit in our result. 
Result so far: 2501.0
Subtract 315 from 575 to get 260.
Take the next digit (2) from the dividend and append it to 260, then repeat: 2602 / 315

Moving on to step 7:
315 goes into 2602 8 times with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 25018.0
Subtract 2520 from 2602 to get 82.
Fetch the next digit (0) from the dividend, attach it to 82 and continue: 820 / 315

On to step 8:
The number 315 fits into 820 2 times, leaving a remainder of 190.
The number 2 becomes the next digit in our result. 
Result so far: 250182.0
The remainder is 190 after subtracting 630 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 9:
If we divide 1900 by 315, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 250182.6
The remainder is 10 after subtracting 1890 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 315 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 250182.6
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
315 goes into 1000 3 times with a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 250182.603
Subtract 945 from 1000 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 12:
550 divided by 315 is 1 with a remainder of 235.
Record the quotient 1 as the next digit in the result. 
Result so far: 250182.6031
If we take 315 away from 550, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 13:
315 goes into 2350 7 times with a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 250182.60317
The remainder is 145 after subtracting 2205 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 14:
If we divide 1450 by 315, we get 4 and a remainder of 190.
The next digit of our result is 4. 
Result so far: 250182.603174
Subtracting 1260 from 1450 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 15:
When dividing 1900 by 315, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 250182.6031746
Subtract 1890 from 1900 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 16:
315 can be fit into 100 0 times, resulting in a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 250182.6031746
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 250182.6031746 with a remaining 1e-07.
